Question 1
Janet is a 30 year old woman who has been recently diagnosed with a herniated
disc at the level of L5-S1. She is currently in the emergency room with suspicion of
cauda equina compression. Which of the following is a sign or symptom of cauda
equina compression?
a. gastrocnemius weakness
b. reduced or absent ankle reflexes
c. numbness of the lateral foot
d. paresthesia of the perineum and buttocks
Answer: d. paresthesia of the perineum and buttocks
Rationale: Cauda equina compression is a surgical emergency characterized by
compression of the spinal nerve roots below the conus medullaris. Classic signs include
saddle anesthesia (paresthesia of the perineum and buttocks), bilateral leg pain or
weakness, and bowel/bladder dysfunction. The "saddle" distribution corresponds to the
S2-S4 dermatomes. While options a, b, and c may occur with isolated nerve root
compression (such as L5-S1 herniation affecting S1 roots), the presence of perineal
paresthesia is the hallmark sign of cauda equina syndrome requiring emergent surgical
decompression.
Question 2
The patient has acute pancreatitis with 7 of the diagnostic criteria from Ranson's
Criteria. In order to plan care, the clinician understands that this criteria score has
which of the following meanings?
,a. a high mortality rate
b. an increased chance of recurrence
c. 7% chance of the disease becoming chronic
d. all of the above
Answer: a. a high mortality rate
Rationale: Ranson's Criteria is a prognostic scoring system used to assess the severity
and mortality risk in acute pancreatitis. A score of 7 indicates severe pancreatitis with a
mortality rate of approximately 60%. The Ranson's criteria include 11 parameters (5 at
admission, 6 within 48 hours) that predict morbidity and mortality. Higher scores
correlate with increased mortality rates: 0-2 = <1% mortality, 3-4 = 15-16% mortality, 5-
6 = 40% mortality, and 7+ = >60% mortality. The scoring system does not predict
recurrence or chronicity of the disease.
Question 3
Reuben, age 24, has HIV and just had a routine viral load test done. The results
show a falling viral load. What does this indicate?
a. a favorable diagnostic trend
b. disease progression
c. the need to be more aggressive with Reuben's medications
d. the eradication of the HIV
Answer: a. a favorable diagnostic trend
Rationale: A falling viral load in an HIV-positive patient indicates that antiretroviral
therapy is effective in suppressing viral replication. This is a favorable trend suggesting
that the treatment regimen is working and the patient's immune function is being
preserved. A declining viral load is associated with a slower rate of CD4+ T-cell decline
and reduced risk of opportunistic infections. It does not indicate eradication of HIV
, (which is currently not possible) or disease progression. It suggests that the current
medication regimen is appropriate, not that it needs to be more aggressive.
Question 4
Which is the differentiating symptom between labyrinthitis and vestibular
neuritis?
a. symptoms with vestibular neuritis are usually acute in onset, whereas with labyrinthitis
the onset is more gradual
b. hearing loss may be associated with vestibular neuritis, but not with labyrinthitis
c. symptoms with labyrinthitis are usually acute in onset, whereas with vestibular neuritis
the onset is more gradual
d. hearing loss may be associated with labyrinthitis, but not with vestibular neuritis
Answer: d. hearing loss may be associated with labyrinthitis, but not with
vestibular neuritis
Rationale: The key differentiating symptom between labyrinthitis and vestibular neuritis
is the presence of hearing loss or tinnitus. Labyrinthitis involves inflammation of both
the vestibular and cochlear portions of the inner ear, resulting in both vestibular
symptoms (vertigo, nystagmus, ataxia) and auditory symptoms (hearing loss, tinnitus).
Vestibular neuritis involves isolated inflammation of the vestibular nerve, affecting
balance but not hearing. Both conditions typically have an acute onset. The presence of
hearing loss points to labyrinthitis, while its absence suggests vestibular neuritis.
Question 5
A 27 year old female presents with a chief complaint of burning and pain on
urination. She has no previous history of urinary tract infection. What are some
additional symptoms consistent with a diagnosis of lower UTI?
